Migraine in university students: A systematic review and meta‐analysis
European Journal of Pain, Volume 27, Issue 1, Page 14-43, January 2023., 2023 Abstract Background Migraine is a complex, neurobiological disorder usually presenting as a unilateral, moderate to severe headache accompanied by sensory disturbances. Migraine prevalence has risen globally, affecting 14% of individuals and 16% of students and carries many negative impacts in both cohorts.

Opioid peptides in the female reproductive system: physiological implications [PDF]
, 1995 All endogenous opioid peptides derive from three precursor molecules i.e. proopiomelanocortin, proenkephalin and prodynorphin. The endogenous opioid peptides exert their biological effects through opioid receptors. Each endogenous opioid peptide exhibits

Bioactive Peptides: Synthesis, Sources, Applications, and Proposed Mechanisms of Action
International Journal of Molecular Sciences, 2022 Bioactive peptides are a group of biological molecules that are normally buried in the structure of parent proteins and become active after the cleavage of the proteins.

Opioid peptides encrypted in intact milk protein sequences [PDF]
, 2000 peer-reviewedOpioid agonistic and antagonistic peptides which are inactive within the sequence of the precursor milk proteins can be released and thus activated by enzymatic proteolysis, for example during gastrointestinal digestion or during food ...

An opioid-like system regulating feeding behavior in C. elegans [PDF]
, 2015 Neuropeptides are essential for the regulation of appetite. Here we show that neuropeptides could regulate feeding in mutants that lack neurotransmission from the motor neurons that stimulate feeding muscles. We identified nlp-24 by an RNAi screen of 115

Bioactive peptides in storage proteins
Grasas y Aceites, 2000 A review on the bioactive peptides described so far in storage proteins, mainly milk proteins, has been carried out. Bioactive peptides are small amino acid sequences inactives in the native protein, but that can be liberated after hydrolysis of these ...
